Free Agency/Salary Cap Era Dominance

Since the beginning of the free agency and salary cap era in 1993, no coach and team has been more well-known for shrewd moves to stay under the salary cap and bringing in free agents to supplement the talent on his team, and win at the same time, as the New England Patriots.

Belichick continued to bring in major free agents for the Patriots’ other Super Bowl runs. Whether it was Roosevelt Colvin and Rodney Harrison in 2003 or trading for Corey Dillon in 2004.

Belichick has also not been afraid to let star players walk. This includes allowing Ty Law to leave in 2005, Willie McGinest and Adam Vinatieri to leave and trading Deion Branch in 2006 or letting Asante Samuel leave in 2008.

Belichick has also not been afraid to pull the trigger on major trades just prior to the season starting. Trading players like Lawyer Milloy, Richard Seymour and Logan Mankins less than a month before the start of those respective seasons.

Despite all of these moves, the Patriots have continued to win year in and year out.

12 Straight Seasons of At Least 10 Wins Or More

The New England Patriots have had at least 10 wins in a season for 12 straight seasons. The last time the Patriots didn't have at least 10 wins in a season was in 2002 when they went 9-7 the year after winning a Super Bowl.

In this stretch, New England has won 16 games once, 12 games four times, 14 games three times, 13 and 11 games once, and ten games two times.

When the Patriots started this incredible run in 2001, the game was much different then it is today.

The running game was still emphasized and defense's were allowed to be much more physical then they are in the game today.

Today's game features rules that are structured to help the offense score more points and teams, including the Patriots, have had to change the way they play defense and the way they hit, due to the emphasis on concussion prevention.

Through all the rule changes that the league has undergone, the Patriots have still won, year in and year out.

14 Consecutive Winning Seasons

In Bill Belichick's first season in New England, 2000, the Patriots went 5-11 and missed the playoffs for the second straight season. Since then, the Patriots have not had a losing season, not even a .500 season, they've had 14 straight winning seasons.

One of the most impressive seasons still remains the 2008 season. Tom Brady got hurt in the first game and was out for the season and Matt Cassell stepped in to replace him.

The Patriots went 11-5 that year but missed the playoffs due to a tie breaker that they lost.

That particular season has to be one of Bill Belichicks greatest jobs in his time here. Nobody saw the Patriots going 11-5 that season after Brady went down.

In the Brady/Belichick era, the Patriots have been to nine AFC Championship games and have won six of them.

New England is currently in a stretch in which they have gone to four straight championship games, three of which were held at Gillette Stadium.

To put this in perspective, Peyton Manning has lost in the first round nine times in his career and the New York Jets have only ever been to four Conference Championship games in franchise history since the AFL - NFL merger.

To be a final four team in nine of 14 seasons is pretty impressive for the New England Patriots, or for that matter, any other team.

Bill Belichick - Greatest Coach Ever

The number one reason why the New England Patriots (2001-14) are the greatest team of all time is because they have the greatest coach of all time, Bill Belichick.

Belichick now has four Super Bowl Rings which ties him for the most all-time with Chuck Noll, who did it with the Pittsburgh Steelers from 1969-91. However, Belichick gets the edge because he has done it in the salary cap/free agency era, where his teams have undergone significant changes on a year to year basis.

Despite the various roster changes from year to year, Belichick has still won and is by far the most dominant coach of this era.

Bill Belichick has 22 playoff wins which is already more than any other coach in the history of the league and is 103 games over the .500 mark (212-109) in his coaching career.
